Thyroid disorders occur when your thyroid gland becomes unable to regulate its hormone production. The thyroid gland is a significant part of the endocrine system in humans. This system is responsible for maintaining bodily functions in the right manner by releasing hormones and chemicals into the bloodstream.

The thyroid gland produces the hormone thyroxine that helps in the regulation of the metabolism and consequently, it also contributes to maintaining body temperature, blood pressure and heart rate.

What is an underactive thyroid?
Hypothyroidism, also known as an underactive thyroid, is a condition where the thyroid gland produces too few hormones for the body to function properly. Without the necessary hormones, your body's metabolism will slow down and will continue to make other functions slower.

The prevalence of hypothyroidism in the UK is 2% in people younger than 60 and 5% for older people. Thyroid disorders are also five times more likely to occur in females than in males.

An underactive thyroid can lead to serious cardiovascular and heart diseases with time, as well as a greater risk of other health conditions due to weakened immunity.

What causes hypothyroidism?
Hypothyroidism can be caused by a number of diseases and other factors that disrupt your endocrine system or the function of the thyroid gland directly. The most common among these causes is Hashimoto's thyroiditis. Others include:

●      Radioactive iodine treatment

●      Thyroid surgery

●      Radiation therapy

●      Medications for other diseases

●      Iodine deficiency

●      De Quervain thyroiditis

●      Pituitary gland disorders

●      Congenital factors

●      Pregnancy

Hashimoto's thyroiditis
This is an autoimmune disease where your immune system confuses your thyroid cells with foreign cells and attacks them. Hashimoto's thyroiditis will lead to hypothyroidism by making your thyroid gland less efficient and reducing the amount of thyroxine (thyroid hormone) being released.

What are the symptoms of an underactive thyroid?
The symptoms of hypothyroidism are difficult to pinpoint. These signs often arise for a very long duration after the onset of the condition. The effects of underactive thyroid are also different among people based on their age, gender, lifestyle and other factors.

Early symptoms include weight gain and fatigue. However, these conditions are also common for ageing and other diseases. In case of sudden weight gain and serious day fatigue, you should consult your doctor immediately.

Refrain from self-diagnosing yourself and ignoring symptoms because hypothyroidism often shows serious signs in the late stages. Some symptoms unique to the condition are dry and scaly skin and brittle nails.

Other common symptoms include:

●      Tiredness/ fatigue

●      Sudden weight gain

●      Frequently low heart rate

●      Low blood pressure (hypotension)

●      Constipation and discontinuous bowel movements

●      Feeling cold

●      Dry skin

●      Reduced appetite

●      Thin or brittle hair

●      Decreased memory

●      Muscle weakness

●      Joint pains

●      Depression and other mood disorders

Most of these symptoms are related to an extremely slow metabolism which is caused by the low function of the thyroid gland. If you notice a range of these symptoms you should get yourself diagnosed by a specialist as soon as possible.

Hypothyroidism symptoms in adults:

●      Infertility

●      Menstrual changes and reduced flow

●      Anemia during pregnancy

●      Erectile dysfunction in men

Hypothyroidism symptoms in children:

●      Oversleeping

●      Delayed growth

●      Constipation

●      Difficulty with feeding and eating

Rare and severe symptoms:

●      Anemia

●      Hoarseness

●      Sensitive skin

●      Loss of hearing

●      Coma

Diagnosis and treatment for hypothyroidism
Thyroid disorders are diagnosed by blood tests or imaging tests. In the case of hypothyroidism, your blood test will show signs of low thyroid activity and fewer thyroid hormones in the blood sample.

Imaging tests are carried out by using radioactive iodine to track the changes in your thyroid's iodine uptake. The thyroid hormone changes from one type to another T3 and T4. For this process to take place it needs iodine. In the screening test, if your thyroid takes up very little or no amount of radioactive iodine it indicates that you have an underactive thyroid.

The frontline treatment for hypothyroidism is medication. This includes thyroxine hormone pills to alleviate the symptoms and fulfil the body's demand for the thyroid hormone and function properly.

You can be prescribed generic Levothyroxine pills or the best Levothyroxine brand UK, Teva. An alternative could be the Euthyrox 100 to buy the online UK.

What is Levothyroxine and how does it work?
Levothyroxine is a synthetic version of thyroxine or the T4 hormone produced by the thyroid gland. These pills are prescribed to treat an underactive thyroid. The synthetic hormone makes up for the lack of natural thyroxine in your body due to hypothyroidism.

Your prescription for Levothyroxine will depend on how severe your symptoms are. These pills are available under many brand names or generic versions and can also be found in several potencies.

You can buy Levothyroxine 100mcg, buy Levothyroxine 50 mcg online or buy Levothyroxine 25 mcg online.

Where can I buy Levothyroxine online?

Although medical science has advanced beyond conventional medications, any treatment that interferes with your natural body functions is likely to cause harmful side effects in the long run. As experts, we suggest that taking precautions should be your first priority to maintain long-term good health.
